Ice crystallizes in a hexagonal lattice having volume of the unit cell as 132 × 10 –24 cm 3 . If density is 0.92 g cm –3 at a given temperature, then number of H 2 O molecules per unit cell is –
Text Solution
Verified by ExpertsThe correct answer is:
D
= d
Mass of n molecules of H 2 O in hexagonal packing = 
= 
= 
= 0.92
∴ n = 
= 4
